Abstract (en)

[origin: WO9725561A2] A flexible pipe (11) for subsea installation has a fluid impervious tube (13) surrounded by a structure pipe (21). The structure pipe (21) is a cylindrical monolithic member. It has at least two rows of slots (23) extending along the length of the wall. The slots (23) are evenly spaced apart, parallel and located on a helix (31). Each of the slots are in a row, which is also located on a helix (25), but extending in a different direction from the slot helix (31). Solid bands (27) extend between the rows of slots (23). Arc members (33) are located between each of the slots, the arc members (33) joining the bands (27). The structure pipe (21) surrounds a fluid impervious tube (13) which is corrugated.
